Certified Inc
5.0
My house had a built-up roof at the end of its serviceable life and an aging skylight. I consulted several roofers experienced in flat roofs and opted for Certified because Tom, the owner, and Steve were extremely knowledgeable and direct and the quote was competitive. They explained the options, recommended TPO, and explained its advantages over the alternatives. Tom and Steve were subsequently very patient with me, answering all of my questions over a couple calls and honoring the price in their original proposal despite my lengthy procrastination. While I didn’t observe the work itself, the estimate was a one-day project but the work team ended up coming back for a few hours on a second day, by which I infer they were attentive to doing the job right.

MG Roofing LLC provided excellent service from the beginning of the project until the very end. Mr. Marvin was very prompt, professional, courteous and skilled. He provided a very reasonable quote within one day as well as pictures of the progress being made on the replacement of the roof until it was completed. I would highly recommend MG Roofing LLC.

Certified Inc. replaced my 80 year old metal flat roof with a new TPO roof in May 2020. When getting an estimate from Certified, Tom explained the process and the recommended roofing system in great detail. He also responded to my follow up questions quickly. After doing some research on different roofing systems, I decided to go with the TPO roof for it's environmental friendly qualities. The team who replaced my roof worked quickly and did a good job of cleaning up after they completed the work. I received pictures of the roof after the work was completed. Every staff person I came into contact with was friendly. Only time will tell me the overall quality of the roof/work done. But I can say I am pleased with the process of getting my roof installed with Certified, Inc.

Very, very well. The only delay was due understandably to weather. They were an absolute pleasure to do business with. I would call them again and refer them to anyone without hesitation.

I was desperate. I had a leak in my roof on December 16, 2009 and water had come into my basement, two bedrooms and the living room. A big snow was predicted and I wanted the new roof right away. I got several estimates. Marvin (M G Construction) was the cheapest and he could do it before the snow. Marvin was very accommodating, easy to work with and did exactly what he said he would do. He completed the job at 5 pm on Friday December 19, 2009 and the big snowstorm (20 inches) began at 9 pm Friday night! I was thrilled to have the new roof! I asked him to come back two weeks later to check on the roof after the big snowstorm. He did and all was well. I would highly recommend him.

This was as painless as a new roof could be. Tom is incredibly communicative and keeps you informed every step of the way. The crew arrived on time, kept to the schedule, and did a fantastic job. Their attention to detail with installing TPO on a flat room was very impressive.

Marvin was extremely responsive to our request for a quote to have our flat roof that wraps around 2 sides of the house replaced. We knew it was causing interior water damage along one side of our house. His quote was thorough and professional and he answered our many additional questions. While it took a while between the time we signed the contract and when the work was actually done, that was due to weather and needing to find 2 days in a row without rain. When the weather finally cooperated, Marvin's team showed up promptly at 8am to begin work. They worked more than a full day trying to beat the evening rain to get the roof finished. It turns out much of our wood (deck, railing, plywood) was rotted and had to be replaced. The roof got its first big test the first night during a pretty substantial rainstorm - and it did great. Marvin's team was back on day 2 to finish everything up. We had one issue that developed that day - it turns out one of the workers hit interior electrical wiring with a nail when putting the flashing in that caused the electrical outlets in our bedroom to stop working. An electrician quickly figured out the problem and corrected it. When we told Marvin about it, he immediately offered to pay the electrician's bill. We were very pleased with Marvin and his team's work, their post-project worksite clean-up, professionalism and quality of the work. He's also local to our neighborhood and very familiar with the homes here, which we also appreciated.

They did a great job of getting out here before the next rainstorm and completing the work in one day. The new roof looks great and is holding up very well, and we have better insulation than before.

Jose came out quickly after we spoke on the phone. He was very generous with his time and answered my many questions patiently. The day Jose and his crew came out to replace our roof, with all the material, we realized the roof may not need to be replaced and we might be able to squeeze some more life out of it. Jose did not push to have it replaced even though he came out with his crew and material. He offered to return the material and just patch the problem areas. The crew did so professionally and neatly. All in all, a great experience and Jose truly demonstrated integrity. I would hire them again in a heart beat.

Working with Certified was a pleasure. As a Construction Manager by trade, I appreciate working with a firm that does what they say they are going to do, when they say they are going to do it. Several years ago, I got onto Angies list and received quotes from the three of the best rated roofers. I picked Certified because they knew their business, they were professional, they responded timely, easy to work with and their price was reasonable. We did not need a roof right away and pushed off the work as other items on the house were pressing. This year we decided to get the roof done. All of the folks at Certified were great to work with. I appreciated the communication and follow through from Sales to office manager to on-site foreman to owner. They just made the process work smoothly. Thanks…Great Job.

Crystal Exteriors LLC
5.0
We enthusiastically recommend this hardworking team. To start, Edgar Li's and Jason Lim's attention to detail, clear and patient explanations and fair pricing impressed us. We live in VA and were at first inclined to go with a VA contractor more out of habit than anything. We saw a very positive review for Crystal on Nextdoor and contacted them as well as two others. Crystal Exteriors stood out for their knowledge (well-explained opinions and observations based on facts and experience) and timely and clear communication and pricing breakdown via email, phone calls and safe-outdoor visits as we navigated the proposal details. They replaced the roof (flat roof (50 years old) and slanting roof (25 yrs old)), siding (original), and windows (single pane original) and gutters on our 1950 brick rambler. The workers kept the area clean and answered all questions and concerns, particularly Jamie who oversaw the siding and windows installation. A remarkable transformation not only on the look but on the very real energy savings.

Two weeks after moving into a new home, we discovered, after a heavy rain, that we had a leak in an older flat roof over a bedroom. Tom was extremely responsive and helpful, and even though they don't do roofing repairs (only full replacements), Tom sent his foreman over to patch our roof as an emergency short-term fix while we looked into options for having the old roof replaced with a TPC membrane. There have been heavy rains in the meantime, and the temporary patch has saved us from taking on more water and causing further damage to drywall and floors. We were impressed by Certified's professionalism and responsiveness, and we would have hired them to do the full roof replacement, but they had a 2-3 week backlog due to all the rainy weather, and we needed the work done sooner than that.

Chris is a laid back and personable guy who seems to really know what he is doing. We had a bit of a unique situation that he dealt with professionally and without any drama. His team worked hard (on a hot day) and their work looks good (as far as I can tell). We discussed the job at length and Chris was thoughtful about how to he went about replacing my roof and did it on the exact date I wanted him to. They made a huge mess in my backyard that they cleaned up in less than an hour. So far no issues with their work. Solid company, would definitely recommend.
